What is signal?

Signal is a PHP library that uses native attributes to create always-up-to-date documentation for your codebase. Annotate classes like services, controllers, or jobs and methods with details on routes, validation rules, dependencies, emitted events, and exceptions—then run a single CLI command like `php vendor/bin/signal generate` to output Markdown and JSON files. It solves the classic problem of drifting docs by scanning your src directory (via a simple JSON config) and generating structured reports grouped by component type, keeping everything in sync with real code—not the pcntl_signal php handler or signal app you're thinking of.

Why is it gaining traction?

Unlike static tools or hand-written READMEs, Signal pulls living metadata straight from attributes, covering HTTP routes, auth abilities, caching TTLs, side effects, and DDD elements like aggregates or value objects. Developers love the zero-maintenance JSON output for API portals or AI context, plus Markdown tables that render beautifully for teams. The hook? One command replaces hours of doc updates, especially in attribute-heavy PHP 8.2+ apps.

Who should use this?

Backend PHP developers on Laravel or Symfony projects documenting APIs, jobs, and domain layers. Ideal for teams with CQRS setups, event-driven services, or microservices where controllers need route/validation specs. Skip if you're not using attributes or prefer prose over structured docs.

Verdict

Promising for attribute fans, with solid CLI, config flexibility, and passing tests—but at 10 stars and 1.0% credibility, it's early alpha; watch GitHub issues before production. Worth a spin in a side project to automate your php signal handling docs.
